The easiest way is to graph it based upon the slope (m) and y-intercept (b), in the standard slope-intercept form: y = m (x) + b.
The line above intercepts the y-axis at y = -2, which is b. The slope (m) = rise/run = (y2-y1)/(x2-x1 ); so for the point (-4, 2) to (-6, 4) is:
(4-2)/(-6--4) = 2/(-6+4) = 2/-2 = -1.
So one form of the equation would be:
y = -1x - 2
Now the other form of an equation is point-slope: y-k = m (x-h), where the point is at (h, k)
and if we pick -5 for x (bc 5 it listed in 3 of the answers), the y at x=-5 looks like around +3
so we get: y-k = -1 (x--5)...
y-3 = -(x+5)... therefore D) is the correct answer:
A) =27.2
b) = 30.1
c) =31.2
d) =36.6
answer = D
Answer:
<h2>39.27 cm²</h2><h2 />
Step-by-step explanation:
area of semi circle = π r² / 2
where r = 10/2 = 5 cm
area = π (5)² / 2
= 39.27 cm²
To find the mean add up all the numbers and divide. The mean absolute deviation is the difference.
Answer:
<h2>4.5 N</h2>
Step-by-step explanation:
To convert 1 pounds to its meteric unit in weight, we need to first convert it to kilogram. Using the conversion 1pound = 0.453592 kg
Since Weight of a substance = mass of the substance * acceleration due to gravity
W = mg
Given mass = 0.453592kg and g = 9.8m/s²
Weight = 4.4452016 Newtons
1 pounds is therefore closest to 4.5 units metric of weight
